Question

whY is H2O is liquied and H2S is gas at room temprature​

Answer 1

Answer:In h2o there is hydrogen bonding because oxygen has a high electronegativity(only second to flourine). so, the hydrogen atoms from other molecules of water forms a hydrogen bonds with oxygen resulting in intermolecular hydrogen bonding. ... therefore at room temperature h2o is a liquid and h2s is a gas.

Explanation:

Answer 2

Answer:

In H2O there is a hydrogen bonding between the two molecules because oxygen has a high electronegativity. so, the hydrogen atoms from a water molecule forms hydrogen bonding with oxygen of neighbouring water molecules resulting in strong intermolecular hydrogen bonding. this is why water is in liquid form at room temperature

While in case of H2S the electronegativity of sulphur is low as compared to oxygen. so, the hydrogen bonding with sulphur is negligible in case of H2S, this is why H2S is a gas at room temperature.
